GEORGE L. BROWNELL, OF WORCESTER, MASSACHUSETTS.

Application filed February 27, 1909.

To all whom it may concern.-

Be it known that I, Gnoncn L. BROWNELL, a citizen of the United States, residing at ll'orcestct', in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Twisting'h'lachineS, of which the following is a specification accompanied by drawings, forming a part of the same, in which- Figure 1 represents an end view of so mu h of a twisting machine as is necessary to illustrate the nature and character of my present invention. Fig. 2 is a detached view on a larger scale of a detached portion of the thread guiding mechanism.

Similar reference letters and figures refer to similar parts in the different views.

My present invention relates to that class of twisting machines in which a multiplicity of strands are laid into a single twisted coil, and it relates particularly to the arrangement of the thread guides by which the individual strands are conducted from a series of se 'iarate spools to the twisting mechanism, said guiding mechanism comprising means for wetting the individual strands, when desired, prior to twisting.

Referring to the accompanying drawings 1 denotes a portion of the supporting framework of the machine, partly shown in section and upon which is supported, in the present instance, a rotating spindle 2, a winding spool 53, rotating flaring arms 4Vby which the twisted strand is laid upon the winding spool and rotating stretching drums 5, 5, the several rotative parts being driven by a geared connection with the main driving shafts 6, 7. The above indicated parts of a twisting machine are substantially like those now in common use and form no part of my present invention.

The strands to be twisted, in the present instance five in number, are carried upon individual spools F5, 9, 10, 11 and 12, turning loosely upon Studs each held at an oblique angle to a horizontal plane and supported in an elevated position by an upright extenslon 13 of the framework. From the individual spools 8 to 12 the strands a are conducted (lownward through individual eyes 14. in a plate 15. From the plate 15 the strands, still held separate by the eyes 14, are conducted beneath a guide roll 16 which is carried upon a depending arm 17 attached to a. bracket 18 by which the guide roll 16 Specification of Letters Patent.

is held within an open water pan 19. From the roll 16 the strands pass upward through a curved guide trough 20 to an elevated roll 21 carried upon a stand 22; vertically adjustable upon the stand 22 by means of a set screw 23 is a. plate 24 provided with a series of eyes 25 arranged in a circle concentric with a vertical line which is tangential to the center of the delivery side of the roll 21, at the point 26, Fig. 2. The strands are passed over the top of the roll 21, thence through the eyes 25 in the plate 24, and from the plate 24 they are conducted through a single hole in a die plate 27, by which all the strands are brought together in a line coincident with the axis of the rotating twisting mechanism, forming a single twisted cord at 28, Fig. 1.

The curved guide trough 20 is projected slightly into the path of the strands as they are conducted from beneath the guide roll 16 to the top of the guide roll 21, so that the sides and bottom of the trough serve to collect any excess of moisture and transfer it back to the water pan 19. The adjustment of theplate 24 on the stand 22 allows the angle between the individual strands and the twisted cord to be varied, as desired, the raising of the plate 24 increasing, and lowering the plate 24 decreasing the angle between the individual strands and the axis of the twisted cord 28.

I claim,

In a twisting machine for twisting a multiplicity of strands into a single strand, means for spacing the strands apart, means for cutting the spaced strands, an elevated strand roll for receiving the wet strands spaced apart, a twisting mechanism having its axis of rotation in a plane tangential to said strand roll. an interposed guide plate between said twisting mechanism and said strand roll having a serics'of holes for the individual strands concentric with the axis of said twisting mechanism, and means foradjusting the position of saidplate between said strand roll and said twisting mechanism, whereby the angle between the axis of said twisting mechanism and the individual strands may be varied in order to vary the pitch of the twist in the twisted strand.
